Abstract: The equipment for drilling and reinforcing a borehole (1) of a well comprises a drill pipe string (5) carrying a drill tool (7) at its lowermost end and a downhole treatment device (19) held on the drill pipe string (5) for applying a liner (17) of polymer material at the surface of the borehole (1). The polymer material is a fusible and/or curable material dissolved and/or emulsified and/or dispersed in drilling fluid (9) or mud circulated through the drill pipe string (5) and an annulus between the drill pipe string (5) and the wall (15) of the borehole (1). The treatment device (19) is adapted to concentrate energy for fusing and/or curing the polymer material contained in the drilling fluid (9) in a limited space (25) at the vicinity of the wall (15) of the borehole (1). The treatment device (19) thus focuses its energy in the vicinity of the wall (15) and allows a continuous reinforcing of the borehole (1) simultaneously while drilling. The present invention provides a mounting system (100) for mounting one or more solar panels (S), and comprises a mounting frame (10) having a plurality of elongate mounting members (20) adapted to be arranged and secured spaced apart and substantially parallel to one another, wherein each of the mounting members (20) is adapted to receive an edge region (E) of a solar panel (S) for fixing same such that each solar panel (S) extends between at least two mounting members (20). The mounting frame (10) may further comprise a plurality of elongate support members (70) adapted to be secured on a base structure, wherein the plurality of mounting members (20) are adapted to be rigidly secured on the support members (70). The mounting system (100) preferably comprises at least one retaining element (40) provided on one or more of the elongate mounting members (20) to prevent the solar panel (S) from slipping in an axial or longitudinal direction from the mounting members (20) before the solar panel is affixed thereto. Furthermore, at least one spacer element (50) may be provided on the elongate mounting members (20) along their longitudinal extent, wherein each spacer element (50) at least partially delimits an area (21) on the mounting member (21) for receiving the solar panel (S). The mounting members (20) may also be configured to include an arresting element (36) that prevents the mounting members (20) from slipping or sliding relative to the support members (70) before the mounting members (20) are rigidly secured on the support members (70). The equipment for drilling and reinforcing a borehole (1) of a well comprises a drill pipe string (5) carrying a drill tool (7) at its lowermost end and a downhole treatment device (19) held on the drill pipe string (5) for applying a liner (17) of polymer material at the surface of the borehole (1). The polymer material is a fusible and/or curable material dissolved and/or emulsified and/or dispersed in drilling fluid (9) or mud circulated through the drill pipe string (5) and an annulus between the drill pipe string (5) and the wall (15) of the borehole (1). The treatment device (19) is adapted to concentrate energy for fusing and/or curing the polymer material contained in the drilling fluid (9) in a limited space (25) at the vicinity of the wall (15) of the borehole (1). The treatment device (19) thus focuses its energy in the vicinity of the wall (15) and allows a continuous reinforcing of the borehole (1) simultaneously while drilling.
